Abstract (en)
[origin: EP0347943A2] A ferroelectric chiral smectic liquid crystal composition, comprising at least one compound represented by the following formula (I): <CHEM> wherein R1 denotes a linear or branched alkyl group having 1 - 18 carbon atoms capable of having a substituent; R2 denotes a linear or branched alkyl group having 1 - 14 carbon atoms capable of having a substituent; X1 and X2 respectively denote a single bond, -O-, -O @- or -@O-; m is 0 - 7; and n is 0 or 1; and at least one compound represented by the following formula (II): <CHEM> wherein R3 and R4 respectively denote a linear alkyl group having 1 - 18 carbon atoms and one -CH2- not bonded to X4 in the alkyl group can be replaced with -O-; X3 and X4 respectively denote a single bond, -O-, -O @-, -@O- or -O @O-; and p and q are respectively 0, 1 or 2 with proviso that both of p and q are not 0.
